  • Interesting fact: General Henry Heth (1825-1888) leading a confederate division in the Battle of Gettysburg, was hit in the head by a Union bullet, but his life was saved because he was wearing a hat two sizes too large, with newspaper folded inside the sweatband. The paper deflected the bullet, and the general, unconscious for 30 hours, recovered and lived another 25 years.

Ere flesh felt the quiver of death's dissolving finger;
When man's intuition led without deflection,
To a sure fruition, and a full perfection.

As if in hospital.
